    Guess what you care about

    Q: What exactly does "Double Sperm Locking Technology" do? Is it truly effective?

    A: Its effectiveness is based on widely recognized physical principles, with a dual-ring structure achieving dual effects:

    Single Lock (locking the base of the penis): By providing a moderately tight grip, it limits the rapid venous backflow from the penis, thereby helping to maintain a longer erection and maintain erection firmness and duration.

    Double Lock (locking the base of the testicles): This further slows overall blood flow while also creating a gentle lifting sensation for enhanced stimulation.

    Combined, these two functions can effectively prolong intercourse. While effectiveness may vary depending on individual experience, as a non-drug physical aid, its principles are scientific and safe.

    Q: Who is the vibration function of this product designed for? How does it achieve "all-encompassing pleasure"?

    A: The vibration function is primarily designed to stimulate the female partner, enabling "combined pleasure for both men and women."

    Top probe: Features ridges for precise stimulation of the female G-spot.

    Bottom vibration module: Fits snugly against the female vulva, stimulating the clitoris (C-spot).
    When the male inserts the device and penetrates, the two vibration points work synchronously, stimulating both the female G-spot and the external C-spot, delivering a "combined" and all-encompassing pleasure, greatly enhancing the pleasure experience for both partners.

    Q: Is the material used safe? Will it cause discomfort?

    A: Safety and comfort are our top priorities.

    Material: Made of medical-grade, skin-friendly silicone, it is soft, non-toxic, and odorless, and will not cause allergies or irritation.

    Comfort: The double rings are made of an elastic material and have an ergonomic, streamlined design, providing effective tightening force while avoiding sharp, painful constriction. For first-time users, it is recommended to start with a short period of use to gradually adapt. rest assured.
